a) The licensing issues have been resolved
b) The licensing issues have not been resolved
c) You don't care if at some point in the future, a large number of unsuspecting open source projects get hit with a takedown notice at the whim of Microsoft.

IMHO it is also true for most linux projects. Who know, the PHP, Python, Apahce, Samba, gcc, glibc, gtk, kde, mozilla, openoffice, wine, lazarus, gambas, kdevelop, etc doesn't hurt any M$ patents ? Propbably the most of linux projects can be sued by software patents...

I'm really so sick of hearing this argument. There is a gigantic difference between the fact that you might accidentally be infringing and knowingly infringing.

Of course you can always get hit by a car when crossing the street and of course that doesn't mean you should never leave your house but that does not mean you should cross at a blind corner with your eyes closed! Use the crosswalk or be very smart and careful!

Does this analogy make sense to you?! My god the "you might always be infringing" argument is so idiotic! I believe it only exists so short sighted mono fanboys can just go on without worring about how dumb they are being.

Well, I certainly can name one piece of open source software that seems to be almost guaranteed break a patent of Microsoft.

The problem is that this one piece of software is being pushed by some very influential people as the preferred way of developing Linux desktop application thus jeopardizing all of those desktop applications.
